This sounds unlikely:
The map 0.1 syntax was dropped from FFmpeg three years 
ago iirc.

This is at least misleading:
There are input options (which have to be placed 
before -i) and output options (which have to be placed 
after the filename following -i). There are input and 
output options with the same name. And there are 
global options where the position does not matter.
That said, I don't think there is any difference 
between FFmpeg and any forks with respect to the 
placement of options.

This is correct to the best of my knowledge.
